ok , engine was running the hose going to the IAC fell off causing engine to race reconnected the hose now the idle wont go below 1500 rpm, i checked the IAC valve and its good with a meter and 12volts , the wire conneted to the IAC shows 12v even when engine hot , thought that was used when motor was cold .
also : as for the IAC vavle i removed it to inspect it , i was ablr to move the soleniod freely , before i reinstalled the valve i pushed the plunger foward closing off any vacuum from entering the TB ( since engine is already hot ) started motor ran ok idle normal ,, when i reconnect the wire for the IAC the rpm would go up to 1500rpm and stay there maybe drop a little but still high.
so why would rpm go up when reconnecting the wire for the iac since engine is already hot
thx for any input
